Simply put, Traeger's bottom shelf is 22" x 13.5" (for the 'Lil Tex/Elite and even more space for the Texas) of solid cold rolled powder coated steel that provides additional space for all of those special items that you want readily at your fingertips when you're Traeger'ing up a smoky storm. The shelf easily attaches to the legs of your grill, making it easily accessible. And don't underestimate its strength. This ain't no wimpy shelf. It can hold up to 50 lbs.
